| Abstract |
The CEEMEX-P4 cruise represented the first sampling expedition to the Gulf of Tehuantepec within the frame of a comprehensive project aimed at the study of demersal resources associated with major shrimp (Penaeidae) fishing grounds off the coast of western Mexico. The material was collected in March-April 1991, aboard the R/V "El Puma" (ICML, UNAM). A total of 29 stations were occupied and samples of invertebrates and fishes were obtained with three types of gear: an 80-foot shrimp trawl, a Mediterranean bottom trawl and a modified Agassiz dredge. Fifty-two species of macro-crustaceans were collected; these included 6 species of stomatopods, and 46 species or subspecies of decapod crustaceans (10 Penaeoidea, 3 Caridea, 2 Palinura, 2 Anomura, and 29 Brachyura). As many as 16 species had never been reported previously in the literature for the Gulf of Tehuantepec. Figures available for stomatopods are close to those reported in literature for areas located off the coast of Sinaloa and Nayarit (SE of Gulf of California), in the Gulf of Tehuantepec, Mexico, and in the Gulf of Nicoya, Costa Rica. When compared to what is known of subtidal decapods, however, number of species is comparatively lower in the Gulf of Tehuantepec than in the SE Gulf of California where as many as 107 species, including only a few cryptic species, have been collected. As far as distribution is concerned, the following results were obtained: 1) all species, except one, have previously been recognized as members of the crustacean fauna of the tropical east Pacific; 2) all stomatopods present a distribution ranging from the Gulf of California, Mexico, to Peru, except for Lysiosquilla panamica; 3) most species of decapod are also know from the Gulf of California (or even from further north) to Peru (or even further south), but two species have never been found south of the Gulf of Panama; one does not seem to range south of Nicaragua; two are known south to Gorgona Island, Colombia; seven have never been reported further south than Ecuador; and two have their currently known southernmost limit in the Gulf of Tehuantepec. |
